Buildup Factors

Abstract The effect of buildup factors on absorbed dose rate in air and the effective dose from gamma rays of primordial radionuclides in building materials, was investigated in the article. Specific absorbed dose rates were calculated for the standard concrete room, as well as, for rooms where brick and covering building materials were used. For all room models the Harima (G-P) buildup factors were applied, while for the standard room the Berger’s and Taylor’s buildup factors were used, too. The contribution of the radiation buildup to absorbed dose rate and effective dose was determined as large as 41%.

Room Model

The indoor low gamma dose rate exposures due to Egyptian room building materials are assessed by means of three different techniques: experimentally by using a thermoluminescent dosimeter, theoretically by using the general room model and by the Monte Carlo simulation through the RESRAD-BUILD software. The present study aims at validating the theoretical methods so that it can be amply used for measuring the low dose rates usually associated with the building materials. The measured in door dose rates were in the range of 55.92 ? 14.47 to 86.89 ? 16.68 nGyh?1 de pending on the position inside the room as obtained by the thermoluminescent dosimeter after 5 months' accumulation. Lower dose rates are obtained near the door and windows while higher dose rates are obtained at the center of the room, and close to the extended walls. Comparable results of the dose rates at same positions inside the room are obtained by the RESRAD-BUILD software. The room model is restricted to the room center and also gives comparable results. The three methods showed comparable results, which in turn confirm the recommendation of using theoretical ones, with RESRAD-BUILD software being more accurate.
